UNITED stares PETER ROVAN O, OF CHICAGO, ILLINOIS FUNNEL.

Application filed November 9, 1927. Serial No. 232,605.

This invention relates to new and useful improvements in funnels and more particularly to an attachment for tunnels, whereby to not only provide an air inlet for the dis charge end of the i'unnel, but provide outlet means for liquid material being passed through the funnel, so that in filling a vessel the liquid material will not be wasted.

One of the objects of the invention is the provision of a funnel attachment that can be used for conveying the liquid from a filled receptacle to an adjacent receptacle, so that the liquid will not be spilled from the receptacle being filled and wasted.

Another object of the invention is the provision of a washer attachment for this particular type of tunnel which is of the sleeve type and oi various sizes so that the funnel can be readily used in connection with receptacles having diilerent sized filling openings. V

WVith the above and other objects in view, the invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claims and shown in the accompanying drawings, in which Figure 1 is a vertical sectional view of my improved tunnel showing its application, and a v Figure 2 a cross sectional view on the line 2-2 of Figure 1.

Referring now more particularly to the drawings wherein various numerals are used to designate the several parts throughout the views 1 indicates a container or rather portion thereof which is provided with an inlet opening 2 for receiving the discharge end 3 of the funnel 4. The discharge end 3 of the funnel is taperingin form as is the usual construction of funnels of this type and "formed in one wall at a point adjacent its small end with an opening, While the body of the funnel is formed with a similar opening on the same side of the funnel.

A vent tube 5' has its inner end fitted in the opening in the dischargeend of the funnel while the other end of the tube is passed out through the opening in the body of the funnel and connected. with a flexible tube 6 which may either form an air ventor be used as an overflow to convey the liquid to an adjacent receptacle. Thus should the receptacle become tilled quickly of tunnel, as shown in Figure l with its lower end fitting closely around the end 3 and resting upon an annular bead 8 pref- 'erably of rubber disclosed. The upper end of this collar is closed by means of an inwardly extending annular flange 9 which engages the upper part of the discharge end of the tunnel. The head 8 can be used for supporting the funnel when the tunnel is used for filling a small neck bottle or similar receptacle. I

The collar 7 is provided in various sizes specially with respect to the exterior thereof, so that any size collar may be readily applied according to the size opening into which the discharge end of the funnel is to be fitted, so that the funnel can be readily used with various types of receptacles having different size openings. It will be readily apparent from the foregoing, that when the funnel is placed in position as shown in Figure 1, and the filling operation is proceeded with, the tube 5 provides a suitable vent to permit air to escape from the receptacle being filled. When the liquid beingplaced in the receptacle has nearly reached the top it will pass out through the tube Sand be directed into an adjacent receptacle by means of the tube 6, thus avoiding waste of material through overflow of the receptacle being filled. The device is extremely simple in construction and can be manufactured at a very low cost.

VVhile I have shown and described the preferred embodiment of my invention, it will be readily apparent that various changes and alterations may be carried out without departing from the spirit of the invention or the scope of the appended claims. I

I claim as my invention: I

1. A funnel including-v atapering body, a tapering discharge portion at the smaller end of the body, a vent tube communicating with the exterior of the body and discharge portion at their smaller ends, an annular yieldable bead'surrounding the discharge V and discharge portion at their smaller ends,

portion adjacent its smaller end, a tapering collar euinonnding. the diseharge portion with its smaller 'end bearing against the outer Wall of said discharge portion and engaging the bead, and an annular interned flange at the largerend of the collar engaging the junction of the body of the fun-' nel and the discharge-portion,

2. In a device of theclass described and c mb nat o a u n n lu n t tars-2 ne o y, pe li h ro ewt the sinaller end or thebodyi a 'vent tube corn municating with the exterior of the body an outlet tube connected to the outer end oit the rent tube, an annular yi eldable bead surrounding the discharge portion adjacent its'sinaller end, a tapering collar surroundthe. discharge portion with its smaller end bearing against the outer Wall of said discharge portion and engaging the bead, andan annular inturned flange at the larger end of the'collar engaging the junction of the body ot the funnel and the discharge portion.

In Witness whereof have hereunto set my hand this 26th day 0i Oct. 1927 PETER ROV'ANO.
